its kind of eneded up working as a new connection as we moved into a new flat about 3 months ago and havent set up wireless internet yet. still using wired connection. Tried to get a wireless router from VM, but they wouldnt budge

If you're in a flat and don't need to stream video (which benefits from a quicker connection) between PCs then an 802.11g router should be perfectly adequate. The biggest advantage of the 802.11n is the (supposedly) greater range. Take your pick from any one of these, from about £20 upwards:

I've got a Linksys WRT54G which I'm getting rid of very soon. It's currently running DD-WRT custom firmware but can be flashed back to factory settings if needbe. The Linksys routers are extremely reliable and built on Cisco technology. The only reason I'm getting rid is because I'm moving to ADSL and don't have a need for a Cable/DSL router any more. If not mine, I would recommend a WRT54G. For the record, I happily stream 1080p content from my laptop to my Xbox 360 with no issues using this kit.
